FWIW, SQLiteOpenHelper treats version 0 as the initial state, where the
DB exists, but onCreate hasn't been called yet.
getWritableDatabase:
int version = db.getVersion();
if (version != mNewVersion) {
db.beginTransaction();
try {
if (version == 0) {
onCreate(db);
} else {
onUpgrade(db, version, mNewVersion);
}
db.setVersion(mNewVersion);
db.setTransactionSuccessful();
} finally {
db.endTransaction();
}
}
getReadableDatabase:
SQLiteDatabase db = null;
try {
mIsInitializing = true;
String path = mContext.getDatabasePath(mName).getPath();
db = SQLiteDatabase.openDatabase(path, mFactory,
SQLiteDatabase.OPEN_READONLY);
if (db.getVersion() != mNewVersion) {
throw new SQLiteException("Can't upgrade read-only
database from version " +
db.getVersion() + " to " + mNewVersion + ": " +
path);
}
onOpen(db);
Log.w(TAG, "Opened " + mName + " in read-only mode");
mDatabase = db;
return mDatabase;
} finally {
mIsInitializing = false;
if (db != null && db != mDatabase) db.close();
}

I get the occasional crash report that
android.database.sqlite.SQLiteException: Can't upgrade read-only
database from version 0 to 1
which is totally bogus and might be in the same league as your issue
